Abstract: Water environment numerical model coupling technology is an important method for complicated environmental assessment, prediction, early warning and support of environmental management decisions.A lot of researches on coupling models have been done at home and abroad.However, the theoretical frame of coupling model is still lack of systematic elaboration.The concept and category of coupling mode of water environment model is analyzed.With concluding the types of water environment model coupling, it is found that the tight coupling and loose coupling are the two main coupling modes from the perspective of coupling degree.From the view of coupled mode, the coupling based on mechanism processes and spatial correlation are two major coupling types.Comparing the technical characteristics of different coupling types, it is found that the loose coupling is the main way of coupling water environment models.It is considered that the gradually standardization is the main development trend of water environment model coupling in the future.
